Progress in gastric cancer has been slow, but steady. Historically, patients commonly presented with significant disease related co-morbidity and received treatment of marginal benefit but unfortunately associated with significant toxicity. Today there is no universally accepted reference standard chemotherapy for this disease. However, there is reason for optimism. Meta-analyses of randomized trials have shown a benefit for first-line combination chemotherapy. Current three drug chemotherapy regimens remain toxic, though perhaps less so than previously, and can result in a small but significant survival advantage in carefully chosen patients. Incremental improvements have been observed in both treatment-related toxicity and survival after first-line therapy. More patients are candidates for chemotherapy beyond progression with first-line therapy and response rates with second-line regimens are similar to those seen in other solid tumor malignancies. Although there is no randomized data to support its use second-line treatment should be considered in appropriate patients. Even before the integration of targeted therapies in the treatment of gastric cancer, it was evident that survival for more than 2 years is possible in a subset of patients and large retrospective studies have highlighted clinicopathologic factors associated with improved survival. Presently, with the addition of targeted therapy, especially anti-angiogenic and anti-Her2 therapy, and a better understanding of the biology of the disease, perhaps a sense of optimism should indeed suppress the nihilism commonly associated with this disease.
胃癌的进展虽然缓慢,但一直在稳步前进。历史上,患者通常表现出严重的与疾病相关的合并症,并接受了获益有限但毒性较大的治疗。目前,这种疾病没有普遍接受的标准化疗方案。然而,我们有理由感到乐观。随机试验的荟萃分析显示,一线联合化疗具有获益。目前的三种药物化疗方案仍然具有毒性,但可能比以前小,在精心选择的患者中,可以带来微小但显著的生存优势。在一线治疗的相关毒性和生存方面都观察到了渐进式的改善。在一线治疗后,更多的患者有资格接受化疗,二线治疗方案的反应率与其他实体瘤恶性肿瘤相似。虽然没有随机数据支持其应用,但应考虑在合适的患者中使用二线治疗。即使在将靶向治疗整合到胃癌治疗之前,就已经有证据表明,一部分患者的生存时间可以超过 2 年,并且大型回顾性研究已经强调了与改善生存相关的临床病理因素。目前,随着靶向治疗(尤其是抗血管生成和抗 Her2 治疗)的加入,以及对疾病生物学的更好理解,或许确实应该抑制人们对这种疾病普遍存在的悲观情绪。
